A spinning globe is slowed at a constant acceleration of 0.750 rad/s2 until it stops. One of the points on the equator moves 23.0° in the first 0.700 s of the slowing phase. (a) Find the total angular displacement of the globe during the acceleration phase. (b) Find the initial angular speed of the globe.

During a drive by golfer Ai Miyazato, the angular displacement of her club is zero at the top of the backswing and 120 degrees at the bottom of the downswing just before impact with the ball. What is the angular displacement of the golf club in radians?

A “blink of an eye” is a time interval of about 150 ms for an average adult. The “closure” portion of the blink takes only about 55 ms. Let us model the closure of the upper eyelid as uniform angular acceleration through an angular displacement of 12.2°. A) What is the value of the angular acceleration the eyelid undergoes while closing? in rad/s^2 B) What is the tangential acceleration of the edge of the eyelid while closing if the radius of the eyeball is 1.25 cm? in m/s^2

The wheels of a bicycle (radius 40 cm ) have an angular velocity of 17 rad/s before the brakes are applied. In coming to rest, each wheel rotates through an angular displacement of 7 revolutions. Part A How long did it take for the bicycle to come to rest? ΑΣφ ? S Submit Request Answer Part B How far did the bicycle travel while it was stopping? ην ΑΣφ ? m Submit Request Answer

A car accelerates uniformly from rest during a 25-second time interval at a constant rate of 0.6 m/s2. If the radius of each wheel is 0.330 m, and the tires roll without slipping, what is the angular velocity of the wheel at the end of the given time interval? Express your answer in units of rad/s.

In a high school swim competition, a student takes 1.4 s to complete 2.5 somersaults. Determine the average angular speed of the diver, in rad/s, during this time interval.

The blades on an electric blender are moving with an angular velocity of 296.8 radians/s. When the blend button is pressed, the blades accelerate at a constant value of 302.7 rdians/s^2. Find the angular velocity of the blades after they have moved through an angular displacement of 75.9 rad (radians) with this angular acceleration. Note the unit of radians is abbreviated as rad.

During a trampoline routine, a gymnast is tumbling in the air at 21 rad/s in a tuck position. He then extends into a layout position and doubles his radius of gyration just before landing on the trampoline bed.   How fast is his angular velocity in rad/s at this instant, just before landing on the trampoline bed?
